Phantom 4 /No Image Transmission Signal.....help,please

[Hendricks]

Been flying my Phantom 4 for about 4 months without any problems......and I've been flying Phantoms for over 3 years.
But, today.......

Just before takeoff, my mobile device display reads: ' No Image Transmission Signal '.
That's never happened before.
I check the 'Aircraft Status' and I see the red triangle with the exclamation point in the center.

I tap that and I get this:

' Air Encoder Error ( 0x800000 ) '

I have tried restarting the Phantom and removing the SD card.
Both my controller and the aircraft have the latest software updates.

Anybody had this happen to them?

Anybody have a solution?


Thanks!!

Reading through similar threads to yours, changing out the microSD card seems to have cleared the fault.

Much thanks!

I have heard this should solve the problem. I will change the micro SD card this morning and report back on the results.

Gotta say, I have been hearing of lots of others with very similar problems.
My issue came up suddenly-out of the blue- yesterday. I'd been flying pretty much every day for over a week and, then yesterday, I'm doing my pre-flight checking, and I'm not getting any image on my phone.

I'll see if changing the card works......if, not, then I'll be on the phone to DJI Support first thing Monday morning.

Good luck, I haven't had that error code before but suffered the NITS disease a while back. I cleared the video cache in the app and re formatted the card and away it went. Go figure....

I have swapped out the microSD card and installed a new one.

No luck.

The problem still exists and I have checked to be sure that both the controller as well as the Phantom have the latest software updates.

My next move is to contact DJI Support this morning to see what they have to say..........I'm sure others have had this happen to them, so DJI should have an answer.

As I mentioned before, this problem just appeared the other day after no problems with my aircraft previously......in fact, I had been flying it for about 4 months with no issues.

Right now, I'm grounded until DJI solves this.

Certainly would welcome any comments from others who have had this happen to them.

Thanks

I called DJI Support this morning and spoke with the Phantom 4 technical representative and here is what I was advised:

Given my description of the problem, he told me to perform a full firmware update for both my Phantom 4 and the remote controller.
( He told me to update the firmware on the aircraft first, then do the same thing with the remote controller.)

He told me to use the tutorials on uTube.

Once I perform the updates, he advised the problem should go away.......i could tell from the manner in which he answered my questions that he had dealt with this problem before.

OK, I will perform the updates to the firmware tonight or tomorrow and then I will report back on the result.

Here is the latest update....

As per the instructions from DJI Support, I attached my Phantom 4 to my computer and, using the DJI Assistant 2 program, I checked to see if there were any updates to the firmware.
It indicated there was an update.

I clicked 'Download' and waited for it to finish.

It failed to successfully download.

I retried it.

Failed to successfully download.

This morning I will call DJI Support and see what they have to say now.

I will keep you updated on this.

I suspect that others out there will run into this problem and hopefully this post will ' walk you through' the procedure of what to do.

I have been advised to box up my Phantom and ship it to DJI in California where it will be checked out.

I'm now waiting for an email from DJI with the complete shipping instructions and the shipping label.

Once, I get all that, I will box the Phantom up and take it to the nearest UPS depot for the start of its journey to California.

Looks like I won't be flying for at least 2 - 3 weeks.


I'm updating my story because there will be others out there who come up against this same problem and reading this will help walk you through the process of exactly what to do.

I'll be back when I know more.

I'll be back when I know more.

Thank you....yes, my P4 also has brand new weird behaviour I've never had.Now, I get green screen when flying...it seems there is some issues to the video that is being transmitted from the P4 to my remote controller-iPad.

Thanks , I will try

OK,

Here is the latest.

I have sent my Phantom 4 - via UPS - to DJI in California. It was picked up Monday and should be there Friday.
DJI estimates it'll be there 1 or 2 weeks, then be shipped back to me.

Hopefully they can determine what the issue is and either fix it or replace the aircraft.
Either way, I'm hoping to have my Phantom back by the first week of November.

The big downside here is that I'm missing the great fall colours here in the North-east.


I'll have another update when I receive my Phantom back from DJI.

Update:

Just received an email from DJI Support. They tell me my Phantom 4 has been repaired and it will be shipped back to me within 2-3 business days.

I have asked DJI Support to include with my drone a detailed description of exactly what repairs were done.
Were there parts replaced,etc?

My Phantom 4 was sent to DJI because it would not successfully download updates to its firmware., despite repeated attempts and all sorts of troubleshooting.

I know other Phantom 4 pilots out there have experienced this problem, so I will update this site when I receive my Phantom 4 back and see what they say about the repair work.

Until then.............

Update:

Just received an email from DJI telling me that my Phantom 4 was 'unrepairable' and they are shipping me a replacement via UPS.
There was no explanation why my Phantom 4 was 'unrepairable'.

I immediately responded and asked for a detailed explanation, because I would like to know why my 4 month old Phantom 4(in mint condition with about 10 flight hours) is now deemed to be 'unrepairable'.

I was also having a look at DJI's policy as it relates to drones that are returned to them for repair while under warranty.

DJI points out that you MAY NOT receive a new drone in return for the one you send in for repair.

I emailed them and told them that since my Phantom 4 was just 3 and a half months old and in mint condition, that I expect a new one as a replacement.
Getting a used one as a replacement for my drone would not be fair, in my case.

I totally understand that DJI should be under no obligation to replace drones that have been well used with new ones.
That would not be fair to DJI.

However, in some cases, the drones sent to them for repair are several months old and in mint condition.........
In those cases, it simply wouldn't be fair for DJI to replace those with used drones.

Has anyone out there sent their drone back to DJI for repair........been told that a repair isn't practical, and received a replacement from DJI?

I'd like to know what you received back?

Was it new or reconditioned?

What was the condition of the drone you sent to DJI?

I'd just like to be sure that I will be treated fairly and that if my Phantom 4 sent in for repair is basically new, that I will receive a new replacement.

Because that's fair.

Comments would be much appreciated.

Thanks.......

Hi, Have you contacted DJI Support and asked them what you should do?
They will likely ask you to send it back to them in order for them to take a look.

DJI uses UPS as the shipper for drones that are returned to them in California.

FINAL UPDATE:

DJI in California got back to me and told me my 3 month old Phantom 4 was deemed to be 'unrepairable' and would be replaced.
I have received a brand new P4 in return along with my original controller.

So, I would rate DJI's customer service as first rate.

However, out of curiosity , I asked DJI representatives what was wrong with my drone that would require them to deem it unrepairable?
Despite me asking that question several times, I never received an answer.
Just that technicians had determined that it should be replaced.

So, the transmission issue remains and I have to wonder if a just had a 'dud' or maybe DJI has an issue with a certain number of their P4s.


In my case, just out of the blue one day, my P4 would not successfully download any updates to its firmware.

But, DJI did replace it and I am grateful for that.

he transmission issue remains

After some testing, I think it seems that my iPAD is too old to support all new DJIGO4 apps. When I use my iPhone 7 plus, there are no issues with the transmission.
